It all depends on factors that are still mostly unknown. They range from the design of the new bridge to how swiftly government officials can navigate the bureaucracy of approving permits and awarding contracts.could take anywhere from 18 months to several years, experts say, while the cost could be at least $400 million — or more than twice that.Realistically, the project could take five to seven years, according to Ben Schafer, an engineering professor at Johns Hopkins University.
But experts say it's better to look to more recent bridge disasters for a sense of how quickly reconstruction may happen.Officials, cited the case of the Interstate 35W bridge in Minnesota, which collapsed into the Mississippi River in 2007. The new span was up in less than 14 months. “It doesn’t mean that all of the right boxes won’t get checked — they will,” Tymon said. “It’ll just be done more efficiently because everybody will know that this has to get done as quickly as possible.”
Minnesota Sen. Amy Klobuchar helped to obtain funding quickly to rebuild the I-35W bridge in her state. But she said replacing the Baltimore span could be more complicated. Badie, of George Washington University, said the cost could be between $500 million and $1 billion, with the largest variable being the design.
Whatever is built, steel is expensive these days and there is a backlog for I-beams, Badie said. Plus, the limited number of construction companies that can tackle such a project are already busy on other jobs.
